ASoC: fsl_xcvr: refine the requested phy clock frequency
[ Upstream commit 347ecf29a68cc8958fbcbd26ef410d07fe9d82f4 ]
As the input phy clock frequency will divided by 2 by default
on i.MX8MP with the implementation of clk-imx8mp-audiomix driver,
So the requested frequency need to be updated.
The relation of phy clock is:
sai_pll_ref_sel
sai_pll
sai_pll_bypass
sai_pll_out
sai_pll_out_div2
earc_phy_cg
